All fuses (of any qulaity) are rated for a maximum voltage. Also not usualy in big letters they will have a maximum current they can inturrupt. While looking at the physical size of them, they all look the same. I don't know what the differance is in them, but there must be. I was in a class put on by one of the fuse makers. They said that at one time one of the selling points for so many differant kinds of fuses it that they are made for a specific purpose. Now they have reversed the thinking (selling point) that one fuse will replace many fuses that are similar.
It is really interisting to watch the Fluke meter film on using the wrong fuse in a circuit. Nice demonstration of what can hapen if you hook you meter across the circuit while in a current or ohm range when you really mean to measuer the voltage.
At work I look in the cabinet with fuses and see about 10 differant fuses that are almost the same size and ratings. Some will have slightly differant tips on them so you can not use them in the some fuse holders. Really bad to have to stock so many differant kinds.
